your folder is your website.

Drag a folder onto a USB stick or SD card. Plug it in. It's a real website at your own URL. Pull the drive out — it's gone. No git, no install, no terminal.

Free tier requires a USB stick or SD card — not your laptop's internal drive. Why?

Claim a subdomain See how it works

Three things. That's it.

1

Drag a folder

Onto a USB stick or SD card. Whatever you want your site to be — drop it there. (Free tier is removable-media only; hosted tier works from anywhere.)

2

Plug it in

Double-click the launcher. Your folder is now a live website at you.flashsite.io. The bytes stream from your drive in real time.

3

Unplug to kill it

Close the launcher or pull the USB out — your site goes offline within milliseconds. No magic. You're the server.

your-site/ you.flashsite.io
index.html
about.html
_sub_blog/ blog.you.flashsite.io

_sub_pricing/ pricing.you.flashsite.io

Why this exists

You own it, physically

Your website lives on a drive you can hold. No git repo. No "cloud provider." Pull the USB, take the site with you.

Edits go live in real time

Save the file → visitor's next request reads it. There is no build, no deploy, no "wait 90 seconds for the CDN to invalidate."

Zero install, zero CLI

Drag, click, done. If you can use Windows Explorer, you can run a website. No git, no Node, no terminal.

Real HTTPS, real URL

You get a normal you.flashsite.io with valid TLS. Visitors use Chrome like normal. SEO works. No special browser.

Infinite subdomains, free

Make a folder called _sub_blog — it's now a subdomain. Drag in a thousand folders, get a thousand sites. All at your URL.

When it's off, it's really off

Close the launcher → tunnel dies → real 404. No "shim," no cached copy on someone else's server. Off means off.

Get your subdomain.

Pick a name. We'll email you your starter kit. Drop it on a USB stick or SD card. Plug. Run. Done.

.flashsite.io

Free during private beta. No card, no install. Free kit is locked to the first USB or SD card you launch it from — need 24/7 or internal-drive hosting?
